A-1 © 2000 UW CSE University of Washington Computer Programming I Lecture 21: Course Wrap-up and Look Ahead

A-2 Where Do You Go From Here? At the Seattle campus of UW, the next course is CSE143, "Computer Programming II" A direct continuation of UW's CSE142 CSE143 introduces the C++ programming language At universities on the semester system, the second-semester course is usually called "Data Structures"

A-3 What is CSE143 like? 5 credit hours; 4-5 projects files in later projects (you don’t write all) Students say: "intense", "time-consuming" Language: C++ Initially just like C Learn programming concepts to support writing larger programs Eventually objects + classes (“object-oriented”)

A-4 What is Covered in a 2 nd Course? Lots of programming practice but less class discussion of it Data structures many involving pointers abstract data types (ADTs) Algorithms many recursive Problem-solving & design Foundation for later CS courses

A-5 Going on in C There is much about the C language we haven't covered You have a foundation now to master more advanced C programming features Learning more C may or may not be useful –The advanced features won't necessarily help learn other languages

A-6 Going on to C++ C++ was developed as an extension to C Practically everything we have learned in the course can be used in C++ The syntax is completely identical in almost all cases However, C++ includes some important new concepts which are not part of C These lead to an approach called "object- oriented programming"

A-7 Going on to Java Java in many ways an improved C++ Much of Java syntax is very close to C if, while, for Expressions Java is not as close to C as C++ is There are also new, object-oriented features

A-8 Programming Concepts We used C, but the concepts go beyond the C language Variables; data types; values Conditions; conditional execution Loops; recursion Functions; parameters (including pointers); call/return Data structuring: arrays; structs; combinations Input/Output

A-9 Beyond Programming… Compiler concepts syntax vs semantics; compilation steps; libraries; debugging What is a computer? Visualize memory, CPU, I/O operation Instruction execution, data movement Problem solving Abstraction Functional decomposition, Data decomposition Algorithms

A-10 Building and Understanding Software Software give computer its personality Computers are proliferating I.e., software is. Programs are complex artifacts Compare to a bridge or a novel What's the effect of a small error? Taming complexity Analysis, design, testing, communicating

A-11 Is Programming Hard or is Programming Fun? Programming is hard... NOW YOU KNOW THIS FIRST-HAND! Programming is also fun... NOW YOU KNOW THIS FIRST-HAND, TOO! (I hope...)
